Do I need a permit for water heater replacement in Unincorporated Martin County?
Yes. In Florida, water heater replacement generally requires a permit, and Unincorporated Martin County is no exception.
Whether a water heater swap needs a permit depends on your jurisdiction and the unit. Some jurisdictions exempt a small like-for-like electric replacement, while others require a plumbing permit for any change-out. Any gas water heater, any increase in size or wattage, or any relocation triggers a plumbing or gas permit almost everywhere.

Florida and local notes for Unincorporated Martin County
Martin County's own permitting office is the Martin County Building Department, reachable on (772) 288-5400 at https://www.martin.fl.us/building. Its online permit portal is https://www.martin.fl.us/resources/online-permit-system. It issues permits for the unincorporated county. If your city does not run its own building department, and many smaller Florida municipalities do not, this is the office that will handle the job. Ask whether a like-for-like swap is exempt at your address, since that answer varies between the county and its municipalities. Martin County lists water heater installation and replacement as permitted work, and its HB 803 page names water heater replacements as still needing a permit even under $7,500. Tankless electric water heaters need electrical load calculations to show the existing service can carry the new load.
